I'll have to check deeply-buried lighting source material, but my best off-the-cuff SWAG is a small round light source with the louvers acting as apertures. I did note where the light source was blocked by solids such as the left-hand corner of sofa/divan/couch seat and the image resting on an easel in front of the louvers there were no projected spots on the floor. In short, a chance optical outcome. If interested I'll dig deep and post photographers applied-lighting examples. I feel confident that our list (read "discussion group") 1-8XX-dial-a-physics-friends will provide a more detailed coherent and scientific explanation before then ;-)
